The company notified the EPA and confirmed about 16,000 gallons of transformer oil spilled. Crews have removed, 7,600 gallons of water and mineral oil mixture, Durant said.

They have booms, pads and skimmers near Massard Creek now to protect it and are testing to see if oil got into the creek. The oil did not get in the Poteau River, according to officials.

The oil is clear and it's difficult to see from far away. Durant said the spill doesn't pose a big health risk; however there is a danger of inhaling vapors if you're in the immediate area and individuals may suffer skin irritation if they come into direct contact.

Adam Adams with the EPS said, "it's comparable to vegetable oil, but you don't want to eat it. It's got a toxicity, but it's very low."

Adams said the mineral oil will not hurt wildlife. They expect to have the area cleaned up by the end of the week.
